Well, I mean - cool air alone wouldn't keep a corpse this neatly preserved, yes?

[He'll just gently place the sheet back over "N", in any case, and shut the fridge door. Bye Rapunzel squad member he never knew...

He then moseys so he's about halfway between where Junpei and Higekiri are, and halfway between where Beck is, just in case he needs to move to either side to help A) fend off zombies or B) pull Beck from a trap. To Beck (but it applies to everyone tbh):]

If anything starts to seem off or strange, say so right away.
